Zeiss

The Zeiss lens product portfolio offers a variety of different product solutions. No matter what vision problem wearers are facing, we can be sure to find the right style for their needs within the Zeiss portfolio, regardless of whether they need thin lenses, light lenses, correction for special distances, special filters or treatments to increase their visual comfort.

Essilor

Essilor is the world leader for corrective lenses. The success of the group, which is present in more than 100 countries, is the result of a strategy that has been driven by innovation for more than 160 years. From design to manufacture, the group develops a wide range of lenses to correct and protect eyesight.

Single Vision Lenses

Single vision lenses are to correct one particular eyesight problem.

They are the simplest form of spectacle lens and are made to a single prescription.

Concave lenses correct short sight and are thinner in the centre than at the edge.
Convex lenses correct long sight and are thinner at the edge of the lens.

The curvature of the lens, its thickness and weight will all depend on the degree of eyesight to be corrected.

The lens material will also influence thickness and weight of glasses, as will the size and shape of frame you choose.

Lenses are now made of lightweight plastics, rather than traditional glass.

There is a wide range of choice to suit your prescription and lifestyle. We will advise on the best for you.

Varifocal Lenses

Varifocal lenses come with three prescriptions in one clear lens for near, intermediate and far distances.

As we age we gradually lose the ability to focus on close objects. This normally occurs in our mid-forties as eyes stiffen and muscles that control them change. This is known as Presbyopia and it happens to us all. Signs you may have noticed include:

Reading small print further away
Needing more light to read
Headaches from eye fatigue

Why choose Varifocal lenses over Bifocal?

Varifocal corrects all distances
They are the ultimate corrective option
They have the convenience of having natural vision at all distances in one pair of glasses
Great cosmetic appearance
No visible lines on lenses, unlike Bifocal lenses

We are a Varilux specialist and offer their range of cutting edge lenses. Call or email us for more details.

Bifocal Lenses

Bifocal lenses contain two optical corrections with a distinct dividing line between the two parts. The most common use for bifocals is for correcting presbyopia. This is the condition that tends to occur with age when the eyes become less able to focus at close distances, meaning two different prescriptions are needed. Although varifocals are generally preferred to bifocals, certain prescriptions and lifestyles are better corrected using a bifocal lens.

High Index and Aspherical Lenses

High index and aspherical lenses are recommended for higher prescriptions.

Lenses are made thinner and from lighter material.
Lenses can be stronger and more durable.
Enhance your appearance.
Reduce weight of spectacles.
Frame choice avaliable to you is increased, lens is perfect for rimless.
Perfect for patients with active lifestyles.

Anti-Reflective Coatings

Anti-reflective is a type of coating applied to the surface of lenses. The purpose of an anti-reflective coating is to reduce reflections off the lenses. An anti-reflective coating allows for clearer vision by reducing reflections, allowing 99.8% of the light through the lens and ensuring distractions to your vision are minimal. Your glasses’ appearance is also improved, as others can see your eyes rather than reflections of light.

Scratch-Resistant Technology

Plastic lenses help make glasses lighter and more comfortable, but they’re much more prone to scratches than glass lenses. The high-quality, scratch-resistant technology helps keep lenses from getting scratched.

Antistatic Technology

Hydrophobic Technology

Grease or droplets of water can slide off the surface of lenses treated with this super-slick coating, so the lenses are quicker and easier to clean.

Polarized

Polarized lenses block certain types of light waves. Sunglasses are often polarized to reduce glare from surfaces, such as light reflecting off water or the road ahead. Polarization blocks as much as 50% of the light passing through a lens. The person looking through the lens can still see clearly in most cases, but it reduces the brightness and glare of light.

Self-Tinting Lenses

At Andrew Fletcher Eyecare we offer two main types of self-tinting lenses Transitions and PhotoFusion® by Zeiss.

Transition lenses are equipped with patented, photochromic dyes that enable the lenses to rapidly darken, when they are exposed to ultraviolet light. The greater the intensity of UV rays, the darker the lenses become. When UV light is no longer present (indoors or at night) the lenses fade back to their original state.

Transitions also offer an XTRActive lens which are adaptive sunglasses that go from a tint to a darker tint, depending on how much sunlight is present. These lenses unlike some are able to darken even behind a car windscreen and will darken up to 50% depth.

Sports

Lenses are available for a variety of different sports for example winter sports, swimming goggles, cycling, snooker glasses and golfing to name a few.

These lenses offer different filters and coatings to provide optimum visual comfort.
